Find and simplify an expression for the indicated composite functions. State the domain using interval notation. 2. a) f(x) 3x-1, g(x)Find (go f (x) Simplified Expression: (write in interval notation) Domain:

Use the graph of the function to find its domain and range. Write the domain and range in interval notation. Provide your answer below: domain: range: -7 36 -6 19 + -3 400 -2 8+ 7 6+ 5- 44 3- 24 1+ -10 4 -2- -3+ - - - -4- 44 1 2 +*+ 4 • to

A box is formed by cutting squares from the four corners of a 7"-wide by 9"-long sheet of paper and folding up the sides. Suppose the function ff determines the volume of the box (in cubic inches) given a cutout length (in inches). Write a function formula for f. I wrote. f(x) = x(7-2x)(9-2x) It then asks What is the domain of f? and to write it as an interval. I solved for 7-2x>=0 The answer I put was (0,3.5). it marked it correct.  But for finding the range of f, I kept getting that one wrong.  The answer it said it was is (0, 36.6081). I do not know how they found the range. I thought to evaluate different equations placing 0 as x to find the range. I tried to set it to 0 and solve. When looking up this answer, it says "all real numbers." I'm completely confused.
